Now many young people are traveling around the world on their own, not because they have no one to travel with, but because they prefer to go alone.
Kristina Wegscheider from California first traveled alone when she was at college and believes that it is something everyone should do at least once in their life. “It opens up your mind to new things and pushes you out of your comfortable zone.” Wegscheider has visited 46 countries covering all seven continents.
In foreign countries, with no one to help you read a map, look after you if you get ill, or lend you money if your wallet is stolen, it is challenging. This is what drives young people to travel alone. It is seen as character building and a chance to prove that they can make it on their own.
